Application February 18, 1938, Serial No. 191,232 o claims; (ci. 10s-s)This invention relates to materials used in building construction andmore particularly to ements which may take the general form of ashingle, a clapboard or the like for roofing or 5. siding purposes. 'Theobject is to provide an im proved construction whereby a light, durableand highly weather-resistant sheathing may be pro'- vided for a roof orwall. For convenience in the following description I will use the specicword "shingle".

My invention will be well understood by reference to the followingdescription taken in connection with the accompanying drawing, wherein:

l rig. 1 is a pian View illustrating a stage in the construction oftheimproved shingle;

Fig. 2 is an end view thereof;

Figs. 3 and 4 are rear and iront views respec tively of the completedshingle;

Figs. 5 and 6 are sections respectively on the lines d-l and 8 6 of Fig.3 but on a larger scale; and

Fig. 7 is a simplified view chiedy in vertical section illustrating themethod of applying the shingle.

I will rst describe briey the general construction of the shingle shown.It comprises a core with a bulk-giving body C (Figs. 5 and 6) for whichI prefer to use double-faced corrugated cardboard. This is enclosedwithin a sealed covering of water-resisting material, preferably a sheetof asphalt-saturated craped paper B, which may be of the type describedin my Patent No. 1,984,910, Dec. 18, 1934. At least that portion V ofthe shingle which is exposed 4to the weather is covered with aweather-resisting material, herein light sheet copper as denoted by thesymbol Cu used as a reference letter. This may be of a gauge weighing afew ounces per square foot and may be conveniently characterized asfoil. Referring to Figs. 3 and 4 of the drawing, the .copper covers theentire outer face of the butt portion of the shingle and has its marginsfolded! over on the rear, as seen in Fig. 3. In the present instance theupper end of the shingle and the rear face are not covered, althoughthey might be if desired.

A suitable taper for the shingle may be provided by a diiferentialcrushing of the corrugations, as illustrated in Fig. 6. It may beremarked y here that for simplicity the corrugated central sheet of the4board has in Fig. 6 beenshown by a single line while Fig. 7 has beenfurther simplided and it has not been attempted to indicate therein bysection lining all the various thicknesses of material utilized in theconstruction more fully illustrated by the other figures.

The core C may consist of a plurality of thicknesses of corrugated boardto give proper bulk i0 and in the illustrative example of the inventionI have shown such multiple thicknesses as anorded by suitable foldingof. a single sheet; Referring to Fig. 1, the core C there comprisesacentral body portion I0 and lateral portions I2 of-lesser heightdefining" a downward extension il. As 5 will appear, the length of thewings I2plus a half the vertical length of the extension it correspondssubstantially to the length of the nished shingle when it is in place.The wings i2 are half the width of the central body It and 10 areadapted to be folded over thereon, and fold lines i6 are here formed bycrushing down the corrugated board toward one side thereof, ythe furtherside viewing Fig. 1, so that the material in these zones is disposedsubstantially in the 15 plane of the outer covering sheet forming asheet-like connection between the central body and the wings of a widthsubstantially equal to the combined thicknesses of the connected parts.A transverse fold-line I8 is similarly formed mid- 20 way of theextension il so that if the distal end of the ,latter is foldedmup itwill reach substantially to the lower edges of the wings i2.

The blank for the core, as shown in Fig. 1, may be disposed upon thesheet 8 of asphalt-saturated paper, of slightly greater height and ofsufficient 25 width to provide the overlap margin 20. The face of thecore, as seen in Fig. 1, may be coated with asphalt and the two wings l2then folded upwardly, viewing the figure, over against the face qf themain body lo, the outer edges of the 3- wings abutting centrally of thecentral portion ill. As seen in Fig. 3, the margin 20 will form anoverlap sealing the covering longitudinally of the shingle and the'papert is pressed `down to the '35 contour of the enclosed core andsealed as is facilitated by the somewhat expansible character given itby craping. 'I'he upper end of the shingle may then be rolled or pressedto crush the corrugations of the core differentially and provide thetaper illustrated in Fig. 6. I'he lower or butt portion of the shinglemay then be covered with dthe foil Cu, the folded over margins or angesof the latter being pressed into close adherence to the body, as ispermitted by the light and flexible character of the metal. The sheetingis securely held by the asphalt with which the paper 8 is saturated.Forl clearness I have here, described the folding zone i8 as formedinitially in' the core blank. If desired, it might be formed 50 afterthe core is covered, the elasticity of the craped paper covering 8 andthe malleability of the copper permitting this Vtobe done.

f As so far described, the shingle has the form shown in Fig. 6 with atapered upper portion 55 comprising two thicknesses of corrugated board,the outer of which extends therefrom dening an inner shoulder 22 (Fig.6), and this`extending portion has the forwardly depressed folding zoneIl substantially midway of its length. The lower 15 to denne fold lines,the board being folded along portion of the extension Il maybe foldedrearwardly relative to the body of the shingle, bringing its distal edgeopposite the shoulder 22 and providing a uniform tapered structurewith'the weather-resistant coating such as the copper foil Cu extendingunbroken around the thick butt thus provided. Thus in applying theshingles to a building they may be placed in position with the taperedend downwardly and the left hand side, viewing Fig. 6, outwardly andnailed through the distal portion of the extension I4 outwardly of thecrease line I8. The main body of the shingle may then be folded up aboutthis line, covering over the heads of the nails, as illustrated in theupper portion of Fig. 7, and the sheathing completed in this manner.

The method of making the fold at I8 as illustrated in Fig. 6 with somenecessary exaggeration of the thicknesses of the various layers, andsimilarly the folds at I6, permit a square joint with a firm edgecomprising the compacted thicknesses which are formed by the crushinginto a sheet-like formation and which bridge over from the relativelyremote faces of the connected parts across the edges of the foldablyconnected sections and provide a firm support for the copper coveringwhich extends unbroken across the fold so made. Moreover, there is nostrain placed upon the copper which might tend to crack or tear it.

I havedescribed a preferred form of the invention but it will beunderstood that a 4building element could be constructed embodying areverselyl folding butt extension wherein the upper tapered portion wasformed in ways other than here described, and` also that the particularmethod of forming a tapered body herein utilized for forming the upperportion of the shingle might be utilized to form elements not includingthe feature of the foldable butt.

I am aware thatthe invention may be embodied in other specific formswithout departing from the spirit or essential attributes thereof, and Itherefore desire the present embodiment to be considered in all respectsas illustrative and not'restrictive; reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.
